I believe CPVC NOT NECESSARY - pipe normally located in a ceiling void, protected by ceiling, in turn protected by sprinklers.
What if fire is in void? Fires don't often start in voids, however IF it did, the melting pipe would melt, release water onto the fire (probably extinguishing it) AND sound the alarm, the CPVC would't. The fire would have to burn through the floor before activating the sprinklers and alarm, by which time the fire could be too well developed for the sprinklers to cope.
i didnt know that you use THAT much wood to build "houses" in the usa. is the whole building made of wood ? i defenitly perfer the old way - concrete and stones. but a sprikler system would be nice anyway.
hehe. You shut them up did'nt ya... People need to read up on things before they go running at the mouth. Anything that can save the homeowner money and still work im all for. I am going to be installing this system in my house. However, I don't like the fact that they do not have a flow switch on it. That would be my only concern.
This Uponor system is approved as a network system in NFPA 13D 3.3.9.4 (2002 edition). The piping is UL Listed in compliance with 1821 (non-metallic Pipe). Hydraulic design is approved with submittal in accordance with NFPA 13D 8.4.3.3 (2002 edition). Per the appendix (B 8.4.3.3) The guy in the video is factory trained, the design calcs are signed by a NICET III / State Level 3 designer, and I'm the AHJ mentioned in NFPA 13D 3.2.2
Approved The Uponor fire protection system meets the National Fire Protection Association (NFPA) requirements for residential fire sprinkler systems. The 1⁄2" Wirsbo AQUAPEX plus tubing and ProPEX fittings are UL-listed for use in multi-purpose tubing systems of residential occupancies as defined in NFPA-13D, the Standard for Installation of Sprinkler Systems in One and Two Family Dwellings and Manufactured Homes. (Uponor received its UL listing in June 2000.)
Show me the section of 13D (specific numbers) that allow this type of pipe in any residential sprinkler system. I have been an engineering manager for 10 years in the industry and have yet to see where ANY clear tube is approved.
Here is the website for the Mfg of the system, I'll get the 2002 NFPA 13D out at the office and post additional information for the good of the order.
Is that that PEX tubing shit? I'm a design technician, but i don't handle a lot of 13R/13D work, we do mostly industrial/manufacturing situations. Those sprinklers have 3 lines in and one line out correct? Crazy stuff, i've seen some prints/schematics and they are confusing to say the least lol.
Here are some references for you, from the 2007 edition of NFPA-13D:
3.3.9.3; A.3.3.9.3;Fig A.3.3.9.3(c);3.3.9.4;A.3.3.9.4;Fig A.3.3.9.4; 5.2.1.3;5.2.2.1;5.2.5.3;5.2.9.1;5.2.10;6.3(2) and (3);A.6.3;Fig A.6.3(c)
I've been designing systems since '81, and doing plan review since '89, and I've seen hundreds of these systems. Guess we're in different parts of the country.
A point well made, see the introductory chapter of NFPA 13D for guidance on this question. Essentially the system is designed to protect occupants for a short time - enough to escape the fire, this system may not save the building. several rooms are exempt from sprinklers, including a garage exemption....
The system piping is manufactured by Upinor (Wirsbo) & is approved for residential fire sprinkler use under National Fire Protection Association stnd. 13D
The deflector part of the sprinkler head has been cut off. This allows the water to flow through the orifice and straight into a bucket for flow testing. k=4.9 for WVC students...
Why not using copper pipes or at least a more durable material?

Wow that's real hardcore. I can't believe NFPA even allows this. Better yet, I can't believe anyone would want to install this stuff.

honestly, you'd be surprised. That's a lot of water, and in MOST cases, it's only 155 degrees to set off a head.
even tho cpvc may not be necessary, it's sure nicer than working with steel

For the record, the system protecting my home and family includes CPVC - installed over 6 years ago...It's a great system - hydraulics are a breeze.
Still have code approved smoke alarm coverage, CO monitor, and local alarm panel...so we're covered on all fronts.
